To all whom it more concern:

Be it lrnown thet ll, Licensee li oorn, e citizen of the lUnited @tetes, end e resident of Pedro Miguel, Genet one, Peneme, heve invented e new end Improved Geuge, ot which the lollowing is e tull, cleer, end erect description.

This inventioirreletes to improvements in ge-uges, perticulerlp toe weter geuge edepte to indicete whet er or not the weter in en eutoinohile redietor hes tellen helow e pre determined level, i

he ohject ot" the invention is to provide e geuge ot this cherecter, which will enehle the driverot e oer to escertein epproirinietely the emount oil weter in the redietor without removing the redietor cepu it. still turtherohject is to provide e de-- vice of this cherecter, which will he simple till end precticel in construction, neet end ettrective in eppeerence, durehle end etticient in use, end coinperetivelv ineepensive to menutecture. p

With thme end other ohjiects in view, the invention consists in certein novel teetures of construction and comhinetions end errengernents ct pert/s, es will he more telly hereinet'ter described end pointed out in the lie the eceompenying drewings ll i re 1 is e view pertlv in. elevetion hut meiny in iongitudinel section through my improved geuge;

lntegrel with the top ol" the trainee t is en edditionel trerne 9, which eceominodetes end supports it ruhher hulh 9. it gless tuhe l9 eirtending through the nipple 't' end trerne t end into the lower end oat-the treme 9 comrnunicete's with the hulh 9. The lower end ot the gless tuhe extends into the redietor tor e predetermined distence. A protecting sleeve such es it they he screwed onto the lower end ot the nipple t eround the tuhe l9 end serves es e not to hold the perts in proper reletionship. The lrerne 8 is provided with an opening such es 19, so thet en operetor noey use his fingers to compress t9 the hulh 9 end such weter into the tube l9, Although it is not shown, the eirposed per-- tion ot vthe tuhe might he protected hy e crgrstel mounted on the treme t.

he tuhe l0 or the plete hehind the tuhe 65 is preterehly marked in some wey to eccentuete the rise oil weter therein when the hulh 9 hes heen squeezedv end releesed. For instence, in Figure 3 T heve shown the ception Full disyed in nerrow letters heclr ot the tuhe. hen the weter rises in the tuhe, these letters will he greetly megnilied in hreedth end eccentuetedn Tn lFigure 2, ll heve illustreted e slight moditicetion wherein e metel tuhe l3 is-l' pessed through en opening it in the indietor cep it. The tuhe et its upper end opens into it hulh to. The tuhe et its lower end is considerehly reduced, es indiceted et it end includes e screw threeded portion 19 so 99 thet e nut 19 mey he utilized to hold the tuhe egeinst movement within the cap.

The operetion ot the device illnstreted in it 1 is es "follows:-

n epplving the geuge, it is first necessery t5 to determine just how low the weter iii the redietor mey hecorne without ep reaching 1 the denger mark. The length of t" e tuhe in eech instence depends upon 'ust where the denger merlr in the pertieul loceted end the end of the'tuhe 19 is loceted slightly shove the denger merlr. en the operator squeezes end releeses the bulb 9 d weter rushes into the tuhe l0 he will lrnow thet he is in no immediete denger of 95 runnin out oil? weter. lt, however, when the hui 9 is squeezed end released, the op eretor t'eils to reise weter-in the tuhe, he will know immediately that more weter should he introduced into the re-dietor. hulh 9 they heve e very small pertoretion therein so thet etter the weter hes heen reised, it will drein heclr into the redietor. This; however, is not essentiel since it the weter remeins in the tuhe 19 end the weter toe in the redietor tells helow the predetermined level, when the operetor egein squeezes the hulh 9 end eepels the weter from the tuhe, he will t'eil to revise weter when the hulh is releesed.

The operation ot the device illustreted in Figure 9 is slightly ditlerent.

er rediet/or is to The too lltl It'has been noted that the tube 13 is greatly reduced at its lower end, as indicated at 17. When the bulb 16 issqueezed, if there is water in the radiator, the bulb will be slow in recovering its normal shape. If, however, the water has fallen below the predetermined level when the bulb 16 is squeezed, air will be quickly sucked into the tube and the bulb 16 will very quickly recover its normal shape. With this form of device, the operator relies upon the rapidity of the recovery of the bulb as disclosed by the sense of touch or the sense of sight to ascertain whether or not the water in the radiator has fallen below the danger line.

It is tobe noted that the details of construction which I have illustrated. show.

merely two of the preferred embodiments of the invention and that a great many slight changes and variations might be resorted to in the construction of the tube supporting means and the bulb actuating means without departing from the invention and hence I do not wish to limit myself to the precise details set forth, but shall consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:
